· Wiring Digrams
4-20 mA
This device is a 2 wire, loop powered transmitter. A voltage of between 9 and 28 VDC must be maintained at this connection. Completion of the earth or system ground is recommended for proper circuit protection.
Power supply voltage must be sufficient to maintain a minimum of 9 VDC at the transducer/transmitter terminals after “dropping” voltage across RL (the equivalent load resistance of the circuit) at full scale current (20 mA). Example: If RL = 250 ohm then “drop” is 0.02 Amps X 250 ohm = 5 volts. Therefore power supply minimum is 5 V + 9 V = 14 V.

0-5 and 0-10 VDC sensors are not as sensitive to circuit loading as 4-20 mA sensors are. As long as the power supply voltage (Excitation voltage) does not exceed 28 VDC, the sensor will operate properly.

Chapter 2: Installation and Removal Procedures and Notes
· Tools Needed
· Wrench sized appropriately for your PT-300’s process connection. · Thread tape or sealant compound for threaded connections.
· Mounting Instructions
Mounting your pressure transducer is easy if you follow a few simple steps: · Never over-tighten the sensor. This can compress the diaphragm, changing how it reacts to pressure. In all cases, tighten the sensor as little as possible to create an adequate seal. On straight threads, tighten only until you feel the o-ring compress – making sure you don’t damage or extrude the o-ring. · Always use thread tape or sealant compound on tapered threads. Wrap thread tape in the opposite direction of the threads so it does not unravel as you screw the sensor into place. Unraveling can cause uneven distribution and seal failure. For straight threads use an o-ring. · Always start screwing in your sensor by hand to avoid cross-threading. Thread failure can be a problem if you damage threads by over-tightening them or by crossing threads.
· Electrical Installation
· Check the pinout table on your PT-300 against your order. · Check that your electrical system wiring matches the pinout table on your PT-300. · For instruments with connectors, make the connection. Otherwise, attach your wires to the provided
terminal strip.
· Removal Instructions
Removing your PT-300 from service must be done with care. It’s easy to create an unsafe situation, or damage your sensor, if you are not careful to follow these guidelines:
· Make sure the pressure is completely removed from the line or vessel where your sensor is installed. Follow any and all procedures for safely isolating any media contained inside the line or vessel.
· Remove the sensor with an appropriately sized wrench (per your process connection). · Clean the sensor’s fitting and diaphragm of any debris (see General Care) and inspect for damage. · Store your sensor in a dry place, at a temperature between -17° and 70° C (0° – 158° F).
DANGER: Removing your PT-300 Pressure Transmitter while there is still pressure in
the line could result in injury or death.

Chapter 3: Maintenance
· General Care
Your PT-300 series pressure transmitter is very low maintenance and will need little care as long as it is installed correctly. However, in general, you should:
· Keep the transmitter and the area around it generally clean. · Avoid applications for which the transmitter was not designed, such as extreme temperatures, contact
with incompatible corrosive chemicals, or other damaging environments. · Inspect the threads whenever you remove the transmitter from duty or change its location. · Avoid touching the diaphragm. Contact with the diaphragm, especially with a tool, could permanently
shift the output and ruin accuracy. · Clean the diaphragm or the diaphragm bore with extreme care. If using a tool is required, make sure it
does not touch the diaphragm.
IMPORTANT: Any contact with the diaphragm can permanently damage the sensor.
Use extreme caution.
· Repair and Returns
Should your PT-300 series pressure transmitter require service, please contact the factory via phone, email, or online chat. We will issue you a Return Material Authorization (RMA) number with instructions.
